A scientist is studying plant growth in a greenhouse and uses her observations to make predictions about future plant development. Which aspect of science does this scenario best illustrate?

• Using evidence to construct testable explanations and predictions

• Making random guesses

• Ignoring data and drawing conclusions

• Relying on tradition instead of evidence

Which of the following best describes scientific methodology?

• A rigid step-by-step process

• A general style of investigation

• A set of laws

• A list of scientific facts

Why is scientific methodology not considered a rigid step-by-step process?

• Because it allows flexibility in investigation

• Because it never changes

• Because it is only used in mathematics

• Because it is not important in science

If you were to design an experiment to test why marsh grasses grow to different heights, which variable might you consider changing based on the image?

• The amount of nitrogen in the soil

• The color of the grass

• The type of animals in the marsh

• The temperature of the air

Which of the following best describes the difference between an inference and a hypothesis?

• An inference is always correct, while a hypothesis is not.

• An inference is a logical interpretation based on existing knowledge, while a hypothesis is a testable explanation.

• An inference is a testable explanation, while a hypothesis is based on random guesses.

• An inference and a hypothesis are the same thing.
